Systems, devices, and methods for machine reading

ABSTRACT

Methodologies, systems, and computer-readable media are provided for reading machine readable features of objects. A local terminal generates a temporary object number corresponding to an unreadable object and captures an image of the unreadable object. A message is sent to a number of portable devices requesting that a duplicate of the unreadable object be located and that a machine readable feature on the duplicate object be read. Once a duplicate object is located, one of the portable devices reads a machine readable feature on the duplicate object, and the portable device calls a service offered by a server to retrieve a data value corresponding to the duplicate item from a database. This data value is then sent to the local terminal invoking a service offered by the terminal to replace the temporary object number with the data value corresponding to the duplicate item.

DETAILED DESCRIPTION

Following below are more detailed descriptions of various concepts related to, and embodiments of, inventive methods, apparatus, and systems for machine reading. It should be appreciated that various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the disclosed concepts are not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

As used herein, the term “includes” means includes but is not limited to, the term “including” means including but not limited to. The term “based on” means based at least in part on.

Example methodologies, systems, apparatus, and non-transitory computer-readable media are described herein to facilitate distributed reading of machine readable features on objects.

Within an enterprise, a user at a local terminal is responsible for reading encoded machine readable features, such as barcodes or QR codes, associated with objects brought to the local terminal. Each object read is assigned a unique object number by the local terminal, and a unique group reference number is generated and assigned to each set or group of objects brought to the local terminal. At times, the local terminal is unable scan certain objects because the machine readable feature is missing, damaged, or otherwise unreadable by local terminal. In such instances, the user typically can pause the scanning process and perform a lookup process. At times, the lookup process requires that another user locate and retrieve a duplicate object that includes a duplicate machine readable feature so that the user can scan the duplicate machine-readable feature on the duplicate object in order to assign the correct object number to the object having the unreadable machine-readable feature. Once this process is completed, the user can continue scanning additional objects in the set. During the lookup process, however, the scanning of additional items often has to be put on hold delaying completion of the scanning of the machine-readable features of each object in the group.

In accordance with some embodiments of the present disclosure, a machine reading system is disclosed that facilitates distributed reading of machine readable features on objects. In some embodiments, once a user at a local terminal has attempted to scan a machine readable feature on an object that is missing or incapable of being scanned or read by the local terminal, the local terminal generates a temporary object number that corresponds to the object with the missing or unreadable machine-readable identifier. The temporary object number is added to a list of scanned objects from the set or group, which is associated with the reference number assigned to that set or group. The local terminal includes a camera or other image capturing device to capture an image of the object with the missing or unreadable machine-readable feature. Once the image is captured, the local terminal can transmit a first message to a server that includes the group reference number, the temporary object number, and the image of the object with the missing or unreadable machine-readable feature.

The server can transmit a second message to a number of portable electronic devices requesting that a duplicate of the object with the missing or unreadable machine-readable feature be located and scanned in situ (i.e., where the duplicate object is found and remotely from the local terminal). The second message can include the temporary object number and the image of the unreadable object so that a user of one of the portable electronic devices can locate a duplicate object based on the image of the unreadable object. Once a duplicate object has been located, the portable electronic device can read or scan a machine readable feature, such as a barcode or QR code, on the duplicate object.

Once the machine readable feature on the duplicate object has been read, the portable electronic device can call a first service offered by the server to retrieve a data value corresponding to the duplicate object from a database. This data value can include attributes and/or information relating to the duplicate item. The server can then generate and send a third message to the local terminal invoking a service offered by the local terminal to replace the temporary object number with the data value corresponding to the duplicate item. Throughout this process, while the duplicate object is being located and scanned in situ, and it's corresponding data value is being retrieved from a database, the local terminal can continue scanning objects and adding those objects to the list of scanned objects from the set or group.

Exemplary embodiments are described below with reference to the drawings. One of ordinary skill in the art will recognize that exemplary embodiments are not limited to the illustrative embodiments, and that components of exemplary systems, devices and methods are not limited to the illustrative embodiments described below.

FIG. 1 is a flowchart illustrating an exemplary method 100 for distributed reading of machine readable features on objects. It will be appreciated that the method is programmatically performed by one or more computer-executable processes executing on, or in communication with the server described further below. In step 101, a reference number module of a local terminal generates a unique reference number corresponding to a selection of objects (a group or set of objects) to be read by an optical reader of the local terminal. The objects in the set or group have been removed from their locations and brought to the local terminal. The reference number identifies one set or group of objects to be scanned from another set or group of objects to be scanned. The local terminal can include, for example, a terminal or kiosk associated with a checkout station within an enterprise.

In step 103, an unreadable object identification module of the local terminal identifies an object with a missing or unreadable encoded machine-readable feature, which is referred to herein as an unreadable object. Examples of encoded machine readable features can include, for example, a barcode or QR code, and the optical reader can include a barcode reader, QR code reader, or any other suitable user-machine interface device regardless of mobility or form factor. In some embodiments, an unreadable object may be identified automatically if the local terminal unsuccessfully attempts to read an object a certain number of times. In other embodiments, an unreadable object may be identified by a user of the local terminal, and the user may provide an input to the local terminal indicating that the object is unreadable.

In step 105, a temporary object number generator module of the local terminal generates a temporary object number corresponding to an unreadable object and inserts the temporary object number in the list of scanned objects for the set or group of objects. The temporary object number serves as a place holder on the list so that subsequent items may be scanned and added to the list.

In step 107, an image of the unreadable item is captured by a camera or image capturing device at the local terminal. The image can be used to assist in identifying the unreadable object and locating a duplicate object that can be scanned in its place. In some embodiments, the user of the local terminal can add additional information about the unreadable object in order to assist in locating a duplicate object. For example, the user can add a brief description of the object or add the department/location from which the object likely originated.

In step 109, a first communication module of the local terminal generates and transmits a first message to a server via a first communication channel. The first message includes, for example, the reference number generated in step 101 and the image of the unreadable object captured in step 107. Once the first message has been sent requesting that a duplicate item be located and scanned, the user of the local terminal can continue scanning objects in the set or group of objects. Scanning is not put on hold, because the temporary object number acts as a placeholder in the list.

In step 111, the server, via a second communication module module, generates and transmits a second message to a number of portable electronic devices (disposed remotely from the local terminal and the server). In some embodiments, the portable electronic devices can communicate with the server over a second communication channel. The portable electronic devices can include a scanning device or optical reader similar to the optical readers associated with the local terminals, or some other type scanner capable of reading machine readable features on objects. The second message includes, for example, the temporary object number generated in step 105, the image of the unreadable object captured in step 107, and a request to locate a duplicate of the unreadable object based on the captured image and read a machine readable feature of the duplicate object. If the original department/location of the unreadable object has been provided by the user of the local terminal, the second message sent out to the portable electronic devices can be sent to portable electronic devices associated with users assigned to be in that department/location, or an additional alert can be sent out to that department/location with the intention of finding users who are relatively close to a duplicate object.

The portable electronic devices can also display one or more tasks that are available to be performed, and users of the portable electronic devices can interact with them in order to select tasks for completion, indicate which tasks they are currently performing, or indicate which tasks have been completed. In some embodiments, if a user of one of the portable electronic devices can identify from which department/location the unreadable object originated, the user can mark the correct department/location at which the duplicate object can be found and an alert may be sent to portable electronic devices associated with user assigned to be in that department/location. In other embodiments, if a user of one of the portable electronic devices decides to begin the task of locating the duplicate item, the user can provide an input to their portable electronic device indicating that they have begun searching for the duplicate object. In such cases, once one user has indicated that they have begun the task of locating the duplicate item, the task can be removed from the rest of the portable electronic devices. If the user who began the task is subsequently unable to locate the duplicate item, the user can push the task back into the queue of tasks available to users on their portable electronic devices.

In step 113, a machine reading module of one of the portable electronic devices reads a machine readable feature on a duplicate of the unreadable object in situ once the duplicate object has been located. Reading the machine readable feature on the duplicate object causes the portable electronic device to call a first service offered by the server. The first service is executed by the server to cause the server to retrieve a first data value corresponding to the duplicate object from a database in step 115, and associate or match the first data value with the temporary object number in step 117. The first data value can include identification and attributes or parameter information relating to the duplicate item.

In step 119, the second communication module of the server transmits a third message to the local terminal. The third message includes, for example, the first data value retrieved from the database in step 115, and invokes a second service offered by the local terminal to replace the temporary object number with the first data value in step 121. Throughout this process, from when the temporary object number is generated in step 105 to when the temporary object number is replaced by the first data value in step 121, the local terminal can continue scanning objects and adding those objects to the list.

FIG. 2 is a flowchart illustrating another exemplary method 200 for distributed reading of machine readable features on objects. It will be appreciated that the method is programmatically performed by one or more computer-executable processes executing on, or in communication with the server described further below. In step 211, a second communication module of a server generates and transmits a second message to a number of portable electronic devices (disposed remotely from the local terminal and the server). In some embodiments, the portable electronic devices can communicate with the server over a second communication channel. The portable electronic devices can include a scanning device or optical reader similar to the optical readers associated with the local terminals, or some other type scanner capable of reading machine readable features on objects. Until step 211, the method proceeds as described above in reference to steps 101 through 109 of FIG. 1. The second message includes, for example, the temporary object number generated in step 105, the image of the unreadable object captured in step 107, and a request to locate a duplicate of the unreadable object based on the captured image and read a machine readable feature of the duplicate object. If the original department/location of the unreadable object has been provided by the user of the local terminal, the second message sent out to the portable electronic devices can be sent to portable electronic devices associated with users assigned to be in that department/location, or an additional alert can be sent out to that department/location with the intention of finding users who are relatively close to a duplicate object. While a duplicate item is being located and scanned, the user of the local terminal can continue scanning objects and adding those objects to a list of scanned objects. Scanning is not put on hold, because the temporary object number acts as a placeholder in the list.

In step 213, one of the portable electronic devices transmits a notification to the server that the search for the duplicate object has begun. As described above, the second message is transmitted in step 211 to a number of portable electronic devices, which can provide a notification to users of the portable electronic devices that a duplicate item needs to be located. In some embodiments, if user of one of the portable electronic devices decides to take on the task of locating the duplicate item, they can provide an input on their respective portable electronic device notifying the server that they have begun searching for the duplicate object. The server can then transmit a fourth message to the local terminal including a notification that the duplicate product is being located. A visual indication at the local terminal can also be provided so that the user at the local terminal can know whether someone has begun searching for the duplicate item.

In some embodiments, if too much time has passed and the duplicate object has not been located and scanned, a manager can be notified. In step 215, a delay tracking module of the local terminal determines whether a specified period of time has passed. If the specified period of time has passed, a notification can be sent in step 217 to notify a manager that the machine readable feature of the duplicate object has not been read. In some embodiments, the notification can be transmitted to a manager terminal or an electronic device used by one or more of the managers. In other embodiments, continuous notifications can be provided to the manager terminal or an electronic device used by a manager in order to provide updates related to the status of a price checking task from start to finish.

In step 219, one of the portable electronic devices reads a machine readable feature on a duplicate of the unreadable object once the duplicate object has been located. In step 221, the terminal can cease providing the visual indication at the local terminal, thus indicating to the user of the local terminal that the duplicate item has been scanned. In other embodiments, the local terminal can provide additional notification, such as an alert on a display device associated with the local terminal or an audio notification, in order to communicate to a user of the local terminal that the duplicate item has been successfully scanned and that price check task is complete.

Reading the machine readable feature on the duplicate object causes the portable electronic device to call a first service offered by the server. This first service causes the server to retrieve a first data value corresponding to the duplicate object from a database in step 223, and associate or match the first data value with the temporary object number in step 225. The first data value can include identification and price information relating to the duplicate item, in some embodiments.

In step 227, the second communication module of the server transmits a third message to the local terminal. The third message includes the first data value retrieved from the database in step 223, and invokes a second service offered by the local terminal to replace the temporary object number with the first data value in step 229. Throughout this process, from when the temporary object number is generated to when the temporary object number is replaced by the first data value, the user at the local terminal can continue reading machine readable features on additional objects.

FIG. 3 is a flowchart illustrating another exemplary method 300 for distributed reading of machine readable features on objects. It will be appreciated that the method is programmatically performed by one or more computer-executable processes executing on, or in communication with the server described further below. In step 301, a reference number module of a local terminal generates a unique reference number corresponding to a selection of objects (a group or set of objects) to be read by an optical reader of the local terminal. The objects in the set or group have been removed from their locations and brought to the local terminal. The reference number identifies one set or group of objects to be scanned from another set or group of objects to be scanned. The local terminal can include, for example, a terminal or kiosk associated with a checkout station within an enterprise.

In step 303, an unreadable object identification module of the local terminal identifies an object with a missing or unreadable encoded machine-readable feature, which is referred to herein as an unreadable object. Examples of encoded machine readable features can include, for example, a barcode or QR code, and the optical reader can include a barcode reader, QR code reader, or any other suitable user-machine interface device regardless of mobility or form factor. In some embodiments, an unreadable object may be identified automatically if the local terminal unsuccessfully attempts to read an object a certain number of times. In other embodiments, an unreadable object may be identified by a user of the local terminal, and the user may provide an input to the local terminal indicating that the object is unreadable.

In step 305, a temporary object number generator module of the local terminal generates a temporary object number corresponding to an unreadable object and inserts the temporary object number in the list of scanned objects for the set or group of objects. The temporary object number serves as a place holder on the list so that subsequent items may be scanned and added to the list.

In step 307, an image of the unreadable item is captured by a camera or image capturing device at the local terminal. The image can be used to assist in identifying the unreadable object and locating a duplicate object that can be scanned in its place. In some embodiments, the user of the local terminal can add additional information about the unreadable object in order to assist in locating a duplicate object. For example, the user can add a brief description of the object or add the department/location from which the object likely originated.

In step 309, a first communication module of the local terminal generates and transmits a first message to a server via a first communication channel. The first message includes, for example, the reference number generated in step 301 and the image of the unreadable object captured in step 307. Once the first message has been sent requesting that a duplicate item be located and scanned, the user of the local terminal can continue scanning objects in the set or group of objects. Scanning is not put on hold, because the temporary object number acts as a placeholder in the list.

In step 311, a second communication module of the server generates and transmits a second message to a number of portable electronic devices (disposed remotely from the local terminal and the server). In some embodiments, the portable electronic devices can communicate with the server over a second communication channel. The portable electronic devices can include a scanning device or optical reader similar to the optical readers associated with the local terminals, or some other type scanner capable of reading machine readable features on objects. The second message includes, for example, the temporary object number generated in step 305, the image of the unreadable object captured in step 307, and a request to locate a duplicate of the unreadable object based on the captured image and read a machine readable feature of the duplicate object. If the original department/location of the unreadable object has been provided by the user of the local terminal, the second message sent out to the portable electronic devices can be sent to portable electronic devices associated with users assigned to be in that department/location, or an additional alert can be sent out to that department/location with the intention of finding users who are relatively close to a duplicate object.

In step 313, the machine reading process is completed at the local terminal. In this embodiment, if too much time has passed waiting for the duplicate item to be located and scanned, and if the rest of the objects to be scanned have been read, the user of the local terminal has the ability to complete the machine reading process before the terminal replaces the temporary object number with a retrieved data value. Because the local terminal generated a temporary object number for the unreadable object, there will be a record of the object on a report or receipt associated with the group of objects read.
